Invasive Alien Species (IAS) can spread aggressively and become dominant in certain areas, thereby compromisng other species. The negative effects of certain IAS are considerable in many countries. IAS are considered as one of the main reasons of biodiversity loss worldwide and can cause major economic damage. In forests, the topic of combating invasive alien plants (IAP) is primarily a question of whether such species threaten or displace native habitats or species, or whether they prevent the rejuvenation of forests that are suited to their location.
Therefore, in this study, we aimed to obtain an overview of how and which IAP have impacts on the regeneration of trees in European temperate broadleaf and mixed forests. In order to address these research questions, we decided to investigate the Central European region in detail. For structure, we used the terrestrial ecoregions classification according to WWF and the Digital Map of European Ecological Regions. We are currently performing a literature review of the different terms pertaining to our research questions to determine how much research is being done in this area. The search is geared to the following questions: (i) which IAP has a direct and/or indirect influence on regeneration (i.e. artificial and natural regeneration) in the forests of Central Europe? (ii) The rejuvenation of which tree species in forests in Central Europe is endangered by IAP? (iii) Which mechanisms or characteristics of IAP affect rejuvenation? and (iv) What management measures and plans are in place to counter the impairment of rejuvenation by IAP and what costs are incurred as a result?
The terms were related to the research questions. Nine search queries with different combinations were performed, and a total of 3,825 hits were obtained. Through systematic literature review, we are reducing the number of research articles in each step, focusing more closely on the research questions. In the end, we hope to show which scientific expertise is currently available on this topic.
